6.5 Solving Quadratic Equations by Factoring
... In Example 4(b) it is tempting to begin by dividing both sides of the equation y 2y by y to get y 2. Note that we do not get the other solution, 0, if we divide by a variable. (We may divide each side of an equation by a nonzero real number, however. For instance, in Example 3 we divided each si ...
